Yes and no, and the correct answer is always - it is an imprecise indicator in the case of oxygen trees.

Typical classification of agricultural areas on 9 levels from VIz to I includes many factors in its methodology, some of which are not very significant in commercial Paulownia cultivation (e.g., water with an installed irrigation system).

What is much more important is the composition of the soil itself. There are plantations on class V soil that thrive, and there are also class II soils that, due to their high clay content, exclude the possibility of cultivating Paulownia.

This is absolutely untrue. This fake news is disproved by the fact that to this day in Middle Eastern countries, Paulownia is planted alongside traditional crops (e.g., corn) because it protects the area from excessive sunlight and enriches the soil with activated carbon. Historically, the first records of Paulownia cultivation in the area of present-day China date back to the 11th century.

We do not know exactly where the myth of "exhausting" the soil by oxygen trees comes from. Paulownia, like any other green plant on planet Earth, absorbs the necessary nutrients and water from the soil.

Of course, due to its exceptionally fast growth, it does this to a proportionally greater extent than traditional forests, but a properly chosen fertilization policy ensures that the plants and soil life receive everything necessary for optimal development.

The first option is to establish a Paulownia plantation on your land as a turnkey investment (along with a package of advisory services), which, thanks to the raw material buyback guarantee, will work for you and future generations, providing a reliable source of income resistant to inflation.

The second option is to buy your land or lease it at a higher price with the option to credit the lease payment towards the purchase. On such land, we usually carry out investments for our corporate clients.

It should have a relatively regular shape, without isolated hills and valleys.

The groundwater level should never rise above 1.5 meters.

The granulometric composition should not include more than 15% clay, and the entire investment should not be located in a floodplain area or subject to legal restrictions (e.g., national parks, Natura 2000 areas, etc.).

The general rule is - the larger, the better. The difference in cost efficiency between establishing a 10-hectare plantation and a 100-hectare plantation is almost a 40-50% reduction in unit cost per tree.

Smaller plantations, even below 1 hectare, can also be managed successfully and profitably, but in the case of cooperation on a lease/buyback basis, we always aim for areas no smaller than 20 hectares.

The basic stage involves remote examination. The result can be seen in the example in the above part of this page. At this stage, in 90% of cases, we can determine whether the given land is suitable for potential Paulownia planting.

Sometimes additionally (especially in central Poland and provinces near the coastal line) we include in the report the study of the average annual wind speed and recorded maximum speeds - this is particularly important for the planting of Paulownia clones with a mix of the "Catalpifolia" species, due to its largest leaves.

Then, in the second step at the advanced stage, we perform a full granulometric analysis by taking samples from depths of 0-30 cm and 30-60 cm from each hectare. This gives us complete information about the soil composition and the planned fertilization policy.

Finally, the final step in the advanced analysis is to perform a soil excavation to check the load-bearing layers and groundwater levels at different times of the year.
